Definitions
- the present invention relates generally to the field of collection and dispensing of fluids, and more particularly to a collection and dispensing system for biological fluids, such as breast milk and/or dietary or medicinal materials.
- Maintaining aseptic integrity is of great importance in many fluid collection and dispensing applications. For example, in the delivery of breast milk or formula to premature infants who are unable to feed regularly, freshness and prevention of contamination are critical. The delivery of enteral fluids is often controlled by regulations and medical standards of practice.
- the present invention provides a container for collecting, storing and dispensing fluid.
- the container includes a hollow tube configured to receive a plunger.
- the present invention comprises a self-venting enteral syringe which includes a syringe body having an outside surface and defining a hollow internal cavity therein, the syringe body including an open end and a substantially closed end opposite the open end, the substantially closed end being integrally formed with the remainder of the syringe body. At least one vent extends from the hollow cavity to the outside surface of the syringe body and a plunger is operable to selectively travel within the hollow cavity. A port is positioned adjacent the substantially closed end.
- the vent is separate from the port and extends from generally adjacent the substantially closed end to outside the syringe body.
- the vent can comprise two vents including a first vent separate from the port and extending from generally adjacent the substantially closed end to outside the syringe body and a second vent formed in the port.
- the port can comprise a double-lumen seal such that a supply/discharge lumen and vent lumen can be extended into the double-lumen port seal.
- the vent is formed in or adjacent the port.
- a removable cap can be provided for covering and uncovering the substantially closed end of the syringe body.
- the integrally-formed, substantially closed end functions as a non-removable cap.
- an offset tip is formed or located in the substantially closed end of the syringe body, the offset tip being positioned in a location offset from a center of the substantially closed end of the syringe body.
- the vent(s) improve the filling of the syringe, while the integral cap provides a better, simpler closure at that end (and makes a separate cap/lid unneeded in most instances).
- the offset tip helps provide better control in the filling and dispensing and is particularly helpful in maintaining uniformity in dispensing from the syringe.
- the optional double-lumen port seal can provide convenient filling/dispensing, while also providing a useful vent. Also, by utilizing the optional female port, a male-to-male connection can improve safety.
- the present invention comprises a self-venting enteral syringe including a syringe body having an outside surface and defining a hollow internal cavity therein and at least one vent extending from the hollow cavity to the outside surface of the syringe body.
- the syringe body includes an open end and a substantially closed end opposite the open end, with the substantially closed end being integrally formed with the remainder of the syringe body.
- a plunger is operable to selectively travel within the hollow cavity, while a port is formed in or adjacent the substantially closed end.
- a vent is positioned in or adjacent the port.
- the present invention is a luer-tip-restricting apparatus for use with liquid transfer equipment.
- the luer-tip-restricting apparatus includes a female port assembly with a hollow body and with a top opening edge, a bottom opening edge and a tapering inner diameter.
- the tapering inner diameter is designed to prevent formation of an air-tight fit with a luer tip.
- the luer-tip restricting apparatus also has at least one stop protruding from the tapering inner diameter. The at least one stop is positioned within the tapering inner diameter to prevent an air-tight fit with a luer tip inserted into the top opening edge of the female port assembly.
- the present invention is a cap for use with a syringe bottle having a conical lid, a female barrel-shaped port assembly and a generally continuous circumferential groove.
- the cap includes a top planar surface with an elliptical shape with a major axis and a minor axis. The major axis is longer than the minor axis.
- the cap includes a generally continuous collar extending from the edge of the top planar surface to a distal edge.
- the collar is constructed of resiliently flexible material.
- the cap includes a pair of opposing grips protruding inwardly from the generally continuous collar. The grips are configured to be removably inserted within the syringe bottle circumferential groove.
- the cap includes a plug that extends from the top planar surface within the generally continuous collar dimensions. The plug is designed to removably insert into the syringe bottle port assembly.
- the present invention is an adaptor for use with a syringe bottle having a conical lid, a female barrel-shaped port assembly and a generally continuous circumferential groove.
- the adaptor includes a resiliently flexible elliptical collar with a major axis and a minor axis.
- the adaptor includes a funnel with a sloping surface and an elongated port with a distal end. The funnel extends within the dimensions of the major axis and the minor axis.
- the adaptor includes a pair of opposing grips protruding inwardly from the elliptical collar and configured to be removably inserted within the syringe bottle circumferential groove.

Description
- The present invention claims priority to U.S. Provisional Patent Application Ser. No. 61/563,923 filed Nov. 28, 2011 and is a continuation-in-part of U.S. Non-Provisional patent application Ser. No. 13/191,721 filed Jul. 27, 2011, the entireties of which are incorporated herein by reference.
- The present invention relates generally to the field of collection and dispensing of fluids, and more particularly to a collection and dispensing system for biological fluids, such as breast milk and/or dietary or medicinal materials.
- Maintaining aseptic integrity is of great importance in many fluid collection and dispensing applications. For example, in the delivery of breast milk or formula to premature infants who are unable to feed regularly, freshness and prevention of contamination are critical. The delivery of enteral fluids is often controlled by regulations and medical standards of practice.
- In addition to proper collection and dispensing of biological fluids, such as breast milk or formula, it is also desirable to provide for the containment, mixing and delivery of pharmaceutical or nutritional supplements. Various consumer and/or professional applications would benefit from improved systems and methods for fluid collection and delivery.
- It is to the provision of improved systems and methods for fluid collection and delivery that the present invention is primarily directed.
- In example embodiments, the present invention provides a container for collecting, storing and dispensing fluid. The container includes a hollow tube configured to receive a plunger.
- In a first example, the present invention comprises a self-venting enteral syringe which includes a syringe body having an outside surface and defining a hollow internal cavity therein, the syringe body including an open end and a substantially closed end opposite the open end, the substantially closed end being integrally formed with the remainder of the syringe body. At least one vent extends from the hollow cavity to the outside surface of the syringe body and a plunger is operable to selectively travel within the hollow cavity. A port is positioned adjacent the substantially closed end.
- In example forms, the vent is separate from the port and extends from generally adjacent the substantially closed end to outside the syringe body. Optionally, the vent can comprise two vents including a first vent separate from the port and extending from generally adjacent the substantially closed end to outside the syringe body and a second vent formed in the port. Also optionally, the port can comprise a double-lumen seal such that a supply/discharge lumen and vent lumen can be extended into the double-lumen port seal. In one example form, the vent is formed in or adjacent the port.
- Optionally, a removable cap can be provided for covering and uncovering the substantially closed end of the syringe body. However, preferably the integrally-formed, substantially closed end functions as a non-removable cap.
- Optionally, an offset tip is formed or located in the substantially closed end of the syringe body, the offset tip being positioned in a location offset from a center of the substantially closed end of the syringe body.
- Advantageously, the vent(s) improve the filling of the syringe, while the integral cap provides a better, simpler closure at that end (and makes a separate cap/lid unneeded in most instances). The offset tip helps provide better control in the filling and dispensing and is particularly helpful in maintaining uniformity in dispensing from the syringe. The optional double-lumen port seal can provide convenient filling/dispensing, while also providing a useful vent. Also, by utilizing the optional female port, a male-to-male connection can improve safety.
- In another example form, the present invention comprises a self-venting enteral syringe including a syringe body having an outside surface and defining a hollow internal cavity therein and at least one vent extending from the hollow cavity to the outside surface of the syringe body. The syringe body includes an open end and a substantially closed end opposite the open end, with the substantially closed end being integrally formed with the remainder of the syringe body. A plunger is operable to selectively travel within the hollow cavity, while a port is formed in or adjacent the substantially closed end. A vent is positioned in or adjacent the port.
- In another example form the present invention is a luer-tip-restricting apparatus for use with liquid transfer equipment. The luer-tip-restricting apparatus includes a female port assembly with a hollow body and with a top opening edge, a bottom opening edge and a tapering inner diameter. The tapering inner diameter is designed to prevent formation of an air-tight fit with a luer tip. The luer-tip restricting apparatus also has at least one stop protruding from the tapering inner diameter. The at least one stop is positioned within the tapering inner diameter to prevent an air-tight fit with a luer tip inserted into the top opening edge of the female port assembly.
- In another example form, the present invention is a cap for use with a syringe bottle having a conical lid, a female barrel-shaped port assembly and a generally continuous circumferential groove. The cap includes a top planar surface with an elliptical shape with a major axis and a minor axis. The major axis is longer than the minor axis. The cap includes a generally continuous collar extending from the edge of the top planar surface to a distal edge. The collar is constructed of resiliently flexible material. The cap includes a pair of opposing grips protruding inwardly from the generally continuous collar. The grips are configured to be removably inserted within the syringe bottle circumferential groove. The cap includes a plug that extends from the top planar surface within the generally continuous collar dimensions. The plug is designed to removably insert into the syringe bottle port assembly.
- In another example form, the present invention is an adaptor for use with a syringe bottle having a conical lid, a female barrel-shaped port assembly and a generally continuous circumferential groove. The adaptor includes a resiliently flexible elliptical collar with a major axis and a minor axis. The adaptor includes a funnel with a sloping surface and an elongated port with a distal end. The funnel extends within the dimensions of the major axis and the minor axis. The adaptor includes a pair of opposing grips protruding inwardly from the elliptical collar and configured to be removably inserted within the syringe bottle circumferential groove.

- With reference now to the drawing figures, wherein like reference numbers represent corresponding parts throughout the several views, the drawing figures depict various embodiments of self-venting enteral syringes according to example embodiments of the present invention.
FIG. 1A shows a self-ventingenteral syringe 10 according to a first example embodiment of the present invention. In general, theenteral syringe 10 includes anelongated syringe body 20, aplunger 40, and an optional cover orcap 60. - Referring now to
FIG. 1C , thesyringe body 20 defines an internalelongate cavity 22 that stretches substantially along the length of the body from anopen end 26 towards a substantiallyclosed end 24. In preferred example embodiments, thecavity 22 substantially matches the cross-section of thesyringe body 20, providing a substantially constant outer-wall thickness of the same. The substantiallyclosed end 24 comprises a supply/discharge port 30 and avent 32, both integrally formed with thesyringe body 20 and positioned generally adjacent the substantiallyclosed end 24. Theclosed end 24 can also include an integrally formed mountinggroove 37 for coupling with the cover orcap 60. - The supply/
discharge port 30 extends from theinternal cavity 22 to the outside surface of thesyringe body 20 along acircumferential wall 31 and surrounds aport seal 34 mounted therein. Theport seal 34 can be an integral flap, and integral fluid seal or a functional seal. Similarly to the supply/discharge port 30, thevent 32 extends from theinternal cavity 22 to the outside surface of thesyringe body 20 along acircumferential wall 33 and surrounds avent port seal 36 positioned therein. Optionally, the supply/discharge port 30 and thevent 32 can be positioned in a position offset from the center of the substantially closed end of thesyringe body 24. The optional offset position ofport 30 and vent 32 can allow a more controlled filling and uniform dispensing of fluids. - The
proximal end 26 of thesyringe body 20 includes anopening 38 for receiving theplunger 40 therein and also includes aflange 23 for supporting the syringe in an upright position and assisting in use of the syringe. Optionally, theflange 23 can have an asymmetric cross section, for example to prevent thesyringe 10 from rolling when lying in a non-vertical position. Thesyringe body 20 can have a substantially circular cross-section (as depicted inFIGS. 1-2 ), or can comprise an oval, elliptical, rectangular, or asymmetric cross-section as desired, and theopening 38 generally has a cross-section that is sized and shaped to snugly receive an insertedcomplementary plunger 40. Theplunger 40 depicted in the figures comprises afirst seal 41 and asecond seal 43 to prevent fluid passage out of the containedvolume 22, and allow the plunger to advance and retract within thesyringe body 20. Optionally, the plunger can comprise one seal or may comprise two or more seals. - The cover or
cap 60, as shown inFIG. 1B , is removably mountable to the substantiallyclosed end 24 of thesyringe body 20 and comprises acircumferential wall 61 extending from acircular lid panel 62 having aperimeter 64. A lower portion of thecircumferential wall 61 comprises a partially circumferential mountingflange 63 for engaging the substantiallyclosed end 24 of thesyringe body 20, for example the mountinggroove 37 shown inFIG. 1C . An upper portion of thecircumferential wall 61 comprises a pinchable orsqueezable rim 68 extending above thelid panel 62. Thesqueezable rim 68 can pivot about theperimeter 64 of thelid panel 62 to disengage the lowerportion mounting flange 63 from the mountinggroove 37, for example to remove theclosure cap 60 from the syringe. Optionally, the closure cap can be attached to the body by a hinge or keeper, or can be non-removable, for example by entirely omitting thesqueezable rim 68 or by having a fully circumferential rim. Additionally, the interior portion of thelid panel 62 comprises a sealingstem 65 andconcentric ridges port seal 34. With the closure cap coupled to the substantiallyclosed end 24 of thesyringe body 20, thestem 65 andridges lid panel 62 are brought into sealing engagement with the top surface ofport seal 34 and ventport seal 36 to provide a more positive seal against the elements. - To ensure a proper circumferential orientation of the interior sealing elements with respect to one another, the
enteral syringe 10 can comprise an exposednotch 28 and theclosure cap 60 can comprise a recessedportion 70. Thenotch 28 and the recessedportion 70 are engagable with each other and ensure proper orientation upon coupling theclosure cap 60 to thesyringe body 20. Additionally, the diameter of thecircumferential wall 61 is substantially equivalent to the diameter of thesyringe body 20. - In additional example embodiments,
FIG. 10 shows a breast pumpattachment port assembly 80 for removably coupling to the substantiallyclosed end 24 of thesyringe body 20. Theport assembly 80 comprises acircumferential wall 81 having a top portion with threading 84 on the exterior surface and a bottom portion surrounding a substantially closedshelf 82. The substantially closedshelf 82 comprises a fill/transfer nipple 86 for extending through theport seal 34 and avent nipple 88 for extending through thevent port seal 36. The fill/transfer nipple 86 (can alternatively be termed a “straw,” “port” or “spike”) comprises an elongated cylindrical tube having a hollow interior portion extending through theshelf 82 to allow fluid communication with the interior of thecavity 22. The vent nipple 88 (can alternatively be termed a “straw,” “port” or “spike”) comprises an elongated cylindrical tube having a hollow interior portion extending along a path to the outside of thecircumferential wall 81. -
FIGS. 2A and 2C show an alternative embodiment of a self-ventingenteral syringe 110, substantially similar to the above-describedsystem 10 with differences as noted below. Thesyringe body 120 defines an internalelongate cavity 122 that stretches substantially along the length of the body from anopen end 126 towards a substantiallyclosed end 124. The substantiallyclosed end 124 comprises a supply/discharge port 130 integrally formed with thesyringe body 120 and extending generally adjacent the substantiallyclosed end 124. The supply/discharge port 130 extends from theinternal cavity 122 to the outside surface of thesyringe body 120 along acircumferential wall 131 and surrounds aport seal 134. Theport seal 134 is sealingly engaged within thecircumferential wall 131 of theport 130 with a tight friction or interference fit and can comprise a double-lumen seal 190 (seeFIGS. 2E-G ). The double-lumen seal 190 comprises a supply/discharge lumen 192 and avent lumen 194. The supply/discharge lumen 192 and thevent lumen 194 can have substantially circular cross-sections (as depicted inFIG. 2G ), or can comprise an oval, elliptical, rectangular, or non-symmetrical cross-sections as desired (as depicted inFIGS. 2E-F ). - The cover or
cap 160, as shown inFIG. 2B , is removably mountable to the substantiallyclosed end 124 of thesyringe body 120 and comprises acircumferential wall 161 extending from acircular lid panel 162 having a perimeter 164. A lower portion of thecircumferential wall 161 comprises a partially circumferential mountingflange 163 for engaging the substantiallyclosed end 124 of thesyringe body 120, for example the mountinggroove 137 shown inFIG. 2C . An upper portion of thecircumferential wall 161 comprises a pinchable orsqueezable rim 168 extending above thelid panel 162. Thesqueezable rim 168 can pivot about the perimeter 164 of thelid panel 162 to disengage the lowerportion mounting flange 163 from the mountinggroove 137, for example to remove theclosure cap 160 from the syringe. Optionally, the closure cap can be non-removable, for example by entirely omitting thesqueezable rim 168 or by having a fully circumferential rim. Additionally, the interior portion of thelid panel 162 comprisesconcentric ridges port seal 134. With the closure cap coupled to the substantiallyclosed end 124 of thesyringe body 120, theridges lid panel 162 are brought into sealing engagement with the top surface ofport seal 134 to provide a more positive seal against the elements. - To ensure a proper circumferential orientation of the interior sealing elements with respect to one another, the
enteral syringe 110 can comprise an exposednotch 128 and theclosure cap 160 can comprise a recessedportion 170. Thenotch 128 and the recessedportion 170 are engagable with each other and ensure proper orientation upon coupling theclosure cap 160 to thesyringe body 120. Additionally, the diameter of thecircumferential wall 161 is substantially equivalent to the diameter of thesyringe body 120. -
FIG. 2D depicts a scaled alternative embodiment of a breast pumpattachment port assembly 180. Theport assembly 180 has acircumferential wall 181 having a top portion with threading 184 on the exterior surface and a bottom portion surrounding a substantially closedshelf 182 having a double-channel nipple 186 (can alternatively be termed a “straw,” “port” or “spike”). The double-channel nipple 186 comprises a fill/transfer channel 187 and a vent channel 188. The fill/transfer channel 187 extends through theshelf 182 to allow fluid communication with the interior of thecavity 122 and is shaped to engage the supply/discharge lumen 192. The vent channel 188 extends along a path to the outside of thecircumferential wall 181 and is shaped to engage thevent lumen 194. Additionally, thecircumferential wall 181 has a partially circumferential mounting flange 188 for engaging the mountinggroove 137 of the substantiallyclosed end 124 of thesyringe body 120. - In operation, the
syringe - All of the components discussed and described herein can be formed from plastics (i.e. polypropolene), other polymers, glass, metals, metal alloys, resins, rubbers, rubber derivatives, elastomerics (i.e. santoprene), silicones or other known materials. In commercial embodiments, the
syringe body elastomer 40, 140 is formed from an elastomeric. Optionally, color additivies may be added to provide protection from UV light and/or colorants may be added to thesyringe - An alternative embodiment enteral-only luer-restricting syringe is described in
FIGS. 3-10 . The luer-restricting syringe allows a single syringe body to receive, store, transport, transfer and deliver fluid within a single chamber. Alid 304 is secured to an open end of acylindrical syringe body 302 through a variety of methods, including friction fit, corresponding threading, tongue and groove, or adhesive. Preferably, thelid 302 is integrally co-molded with thesyringe body 302. Similarly to thesyringe bodies alternative syringe body 302 defines an elongate interior cavity chamber for receiving and storing material, for example fluid. The syringe body 305 has a generally circular circumference. A generallycontinuous groove 312 is extends around the outer circumference between thelid 304 and thesyringe body 302. Thecontinuous groove 312 can be integrally formed with thesyringe body 302. Alternatively, a continuous groove can be formed around the outer surfaces of either the lid or the syringe body. As depicted, thegroove 312 includes a pair ofribs 306 that interrupt the continuity of the groove.Additional ribs 306 can alternatively be included within thegroove 312. Theribs 306 act as barriers to prevent unwanted rotation of adaptors or caps with respect to thegroove 312, as described further below. As depicted, thelid 304 can be generally conical with apeak 308 and a hollow interior. However, alternative shapes can be similarly effective. - As depicted, a female supply/
discharge port assembly 300, including abarrel receiver 314 andchimney insert 318, extends upwardly over an aperture (not shown) in thelid 304. The supply/discharge port assembly 300 can be secured to the lid through a variety of fixation methods, including friction fit, corresponding threading, tongue and groove, or adhesive. Preferably, thebarrel receiver 314 can be integrally co-molded with thelid 304. Thechimney insert 318 is separably secured within thebarrel receiver 314. Thechimney insert 318 can be secured with respect to thebarrel receiver 314 through an interference or friction fit, conjoined through adhesives, bonded through heat, radiofrequency, ultrasonic, or over-molded by molding the barrel receiver over the chimney insert. As further depicted inFIGS. 5A-5C , an integralcontinuous groove 380 extends around the circumferential interior surface of thebarrel receiver 314. As depicted, thebarrel receiver 314 can include a pair of opposingwing recessions 310 defined longitudinally-parallel along the interior surface of thebarrel receiver 314 from the top edge to a defined termination position before reaching thecontinuous groove 380. Alternatively, thebarrel receiver 314 can include a greater or lesser number ofwing recessions 310 positioned at various locations on the internal circumference. As depicted, thebarrel receiver 314 has a circumferential surface with variable height at particular locations between the top and bottom openings along the circumference, thus producing a slanted bottom edge with a minimum and maximum height. - As depicted, the
chimney insert 318 includes anupper region 354, alower region 358 and aneck 370. Thechimney insert 318 is preferably integrally molded as a continuous unitary body and can be constructed of a rigid, durable material, for example plastic or metal. Thechimney insert 318 has aninner passageway 320 with a generally consistent diameter. Theupper region 354 includes a top edge andtransition surface 352 leading into theinner passageway 320. Theupper region 354 can also include a pair of opposingwing protrusions 350 having a substantially similar shape and dimensions as the barrelreceiver wing recessions 310. Theprotrusions 350 are designed to be securely received within thewing recessions 310 in thebarrel receiver 314. Acontinuous ridge 356 protrudes around the circumferential outer surface of thechimney insert 318 and distinguishes theupper region 354 from thelower region 358. Thecontinuous ridge 356 is designed to secure within thecontinuous groove 380 in thebarrel receiver 314. As depicted, theupper region 354 and thelower region 358 can have a generally consistent outer diameter. - The
neck 370 extends from below thelower region 358. Theneck 370 has a smaller outer diameter than the upper 354 and lower 358 region outer diameters, thus producing an overhang of the lower region over the neck. Afinger protrusion 333 extends onto the outer surface of theneck 370. Thefinger protrusion 333 has an outer-surface diameter consistent with thelower region 358, thus creating a generally consistent outer surface across the lower region and the finger protrusion. Thefinger protrusion 333 is designed to be received in afinger recession 378 of a seal, as further described below. As depicted, theneck 370 has a circumferential surface with variable height at particular locations along the circumference between the top and bottom openings, thus producing a slanted bottom edge with a minimum and maximum height. - A pair of
stops 330 protrude from the interior surface of thechimney insert 318. As depicted, thestops 330 are positioned opposite each other along inner surface of thelower region 358 of thechimney insert 318. Alternatively, a single stop or multiple stops can extend from the inner surface of thechimney insert 318. As depicted, thestops 330 can have a tapered inwardly-facing surface that narrows in diameter toward theneck 370. Alternatively, the inwardly-facing surface of thestops 330 can have a consistent diameter. - The
chimney insert 314 has a tapering inner diameter that is designed to receive an enteral-only syringe tip 400, such as shown inFIG. 5B . A commercially-available enteral-only syringe tip 400 has a tapered shape. The inner diameter of thechimney insert 314 has a larger upper diameter and a smaller lower diameter in order to correspond with a commercial enteral-only tip. Upon being inserted into the top opening of thepassageway 320 of thechimney insert 314, the tapered enteral-only tip 400 creates a friction-fit air-tight seal with the chimney at the point when the tapered enteral-only tip 400 diameter matches thechimney insert 314 diameter. As shown, the friction-fit air-tight seal is formed without the enteral-only tip 400 contacting thestops 330. This friction-fit air-tight seal allows fluids to be transferred between the enteral-only syringe 400 and thesyringe body 302 without acquiring outside contaminants. - As depicted in
FIG. 5C , thechimney insert 314 is designed to not create an air-tight seal with a commercially-available luer tip 402, for example a luer-slip-tip, having dimensions defined by ISO 594/1-1986(E) and ISO 594-2:1998(E) conical fittings with a 6% Luer taper for syringes, needles and certain other medical equipment, hereby incorporated by reference for all purposes. A commercially-available luer tip 402, or luer-slip-tip has a smaller minimum diameter and smaller maximum diameter than the enteral-only tip 400. As depicted, thestops 330 prevent theluer tip 402 from extending within thechimney insert 314 to a distance that would be required for theluer tip 402 to form an air-tight friction-fit with the chimney insert. Specifically the distance between thestops 330, specifically the inwardly-facing surface has a maximum of, or is preferably less than, 3.925 mm, which is the minimum diameter for a 6% Luer tip end of the male conical fitting as defined by ISO standards. Additionally, the diameter of the top opening of thechimney insert 318 has a minimum of, or is preferably greater than, 4.315 mm, which is the maximum diameter at the opening of a female conical fitting to receive a 6% luer conical fitting. This inability to form a friction-fit air-tight seal prevents thechimney insert 314 from being effectively used with aluer tip 402 because contaminants cannot be excluded from any liquid being transferred between the luer tip and thesyringe body 302. This meets the provisions of such standards as ISO 80369 by restricting engagement of luer connectors and enteral connectors to prevent intermingling of the fluid paths. - A
seal attachment 362 is depicted to attach with respect to theneck 370 of thechimney insert 318. Theseal attachment 372 has a continuouscircumferential collar 372 that fits around theneck 370 and has an outer diameter that is generally consistent with the outer diameter of thelower region 358 of thechimney insert 318. The continuouscircumferential collar 372 also has afinger cutout 378 to receive thefinger protrusion 333 on thechimney insert 318. - The continuous
circumferential collar 372 is secured around theneck 370 through a friction-fit and/or an adhesive. Theseal attachment 372 includes a pair offlaps 374. As depicted, theflaps 374 have a generally semi-circular shape with a smaller diameter than the interior diameter of the continuouscircumferential collar 372, thus providing a generally-continuous gap 364 between the flaps and the continuous circumferential collar. Theflexible flaps 374 are secured to the continuouscircumferential collar 372 through a pair of bridge mounts 376. As depicted, theflaps 374 are separated by anelongated channel 377. Theseal 362 is preferably constructed as a single unitary body including the continuouscircumferential collar 372, the bridge mounts 376 and theflaps 374. Theseal attachment 362 is preferably constructed of a flexible material, for example plastic, rubber or silicone. - In use, the
seal attachment 372 is secured with respect to thechimney insert neck 372 and theflaps 374 prevent or restrict solid particles from entering or exiting thesyringe body 302 and to augment the flow of fluid into and out of the syringe body. Alternatively, theflaps 374 can be secured directly to thecircumferential collar 372 without thegap 364. Alternatively still, theflaps 374 can resiliently rest together forming an air-tight seal that is only broken with a protruding body, for example a tube or straw, that is forced between the flaps. - As depicted in
FIGS. 11-22 , thesyringe body 302 can be stored or transported standing vertically upright on aplatform 406. In storage or transport, the contents held within the internal chamber ofsyringe body 302 can be protected with aremovable cap 500. - The
cap 500 has a topplanar surface 502 and a generallycontinuous collar 504 extending downwardly from the edge of the top planar surface. Thecollar 504 can have a consistent height from the topplanar surface 502 to a distal edge. The generallycontinuous collar 504 is preferably constructed of resiliently-flexible material, for example plastic. As depicted, the topplanar surface 502 can have an elliptical shape with a major (X) axis and a minor (Y) axis. Afirst pinch recession 508 can be formed at one end of the major (X) axis. Asecond pinch recession 510 can be formed at an opposite end of the major (X) axis. The first 508 andsecond pinch recessions 510 can extend partially along the topplanar surface 502 and generally across the height of thecollar 504. In use, inwardly-directed pinching pressure applied simultaneously to the first 508 and second 510 pinch recessions, along the major (X) axis, causes the resiliently-flexible collar 504 to change its shape to shorten the major (X) axis and lengthen the minor (Y) axis. When this simultaneous pressure is released, the resiliently-flexible collar 504 returns to the pre-pressure relaxed state. - A pair of
teeth grips 514 extend inwardly from the interior surface of thecollar 504. As depicted, the teeth grips 514 can be positioned diametrically opposite each other, and separated by and along the minor (Y) axis. Alternatively, additional pairs of teeth grips at alternative locations can be similarly effective. The teeth grips 514 are preferably integrally co-molded with thecap 500. The teeth grips 514 have a shape that is designed to removably insert into thecontinuous groove 312 between thelid 304 and thesyringe body 302 described above. In a relaxed state without application of a pinching pressure described above, the minor (Y) axis length is shorter than the diameter of thesyringe body 302. In a similarly relaxed state, the minor (Y) axis length is generally equivalent to the distance between opposing points along the inner-most surface of thecontinuous groove 312. In the relaxed state, the resilient force of thecap 500 presses the teeth grips 514 into thecontinuous groove 312, thus preventing the cap from involuntary removal during transport or storage. Correspondingly to that described above, applying a simultaneous major (X) axis pinching pressure to eachpinch recession continuous groove 312 so that thecap 500 can be removed. In use a depicted inFIG. 17 , the teeth grips 514 preferably insert into thecontinuous groove 312 between the pair ofribs 306 to prevent thecap 500 from rotating with respect to the groove. - As depicted, a plug is secured through an aperture (not shown) in the top surface region of the
second pinch recession 510. The plug includes a base that secures above thetop surface 502 and a rigid probe that extends through the aperture (not shown) and below the top surface. The plug is preferably integrally constructed of a unitary single-body construction. The probe preferably is tapered and has dimensions that are generally consistent with an enteral-only tip, similar to thetip 400 described above. Afirst example plug 506 can have an opening in thedistal end 519 of theprobe 518 with a hollow bore extending to aclosed base 516. Alternatively as shown inFIG. 15B , a second example plug can have a base 516B with anopening 517 and a bore that extends into aprobe 518B that has a closeddistal end 519B. Alternatively still, a third example plug can have a solid base and solid probe without any openings or internal bores. - The plug can be separately constructed and then fixed through the
cap 500 through a variety of fixation methods, including friction fit, threading, and adhesive. Preferably, the plug can be integrally co-molded with thecap 500 to form a unitary body. - In use, the
probe passageway 320 in the above-describedchimney insert 318 until it forms an air-tight friction-fit seal similar to that described with the enteral-only tip 400. This seal is air-tight and prevents unwanted material from entering or exiting thesyringe body 302 during storage or transport. - A
rigid support 512 extends downwardly from the topplanar surface 502 within thecap 500. As depicted, thesupport 512 can have a semi-circular wall shape with a disconnect. As further depicted, thesupport 512 can be positioned with respect to thecap 500 such that theplug 506 is positioned within the disconnect of the semi-circular wall shape. As depicted, theplug 506 andsupport 512 can be aligned offset from center along the major (X) axis. In use, when theprobe chimney insert 318, a distal edge of thesupport 512 contacts thelid 304. This contact between thesupport 512 and thelid 304 assists to prevent theprobe chimney 314, as shown inFIGS. 15A-16 . The semi-circular shape of thesupport 512 corresponds with the cone shape of thelid 304 to maintain an even distribution of support. The proximal end of thesupport 512 can be fixed to thecap 500 through a variety of fixation methods, including friction-fit and adhesive. Preferably, thesupport 512 is integrally co-molded with thecap 500 to form a unitary structure. - As depicted in
FIGS. 18-22 , an alternative cap 500A can align aplug 414 andsupport 422, of similar design and structure to plug 506 andsupport 512 described above, along the center of the minor (Y) axis, thus turned ninety degrees and shifted toward center from thecap 500 described above. Similarly to thecap 500 described above, a pair ofteeth grips 416 are depicted to align along and be separated by, the minor (Y) axis. - An
elongated marker 412 can integrally protrude from the outer surface of the cap 500A and extends from the plug downwardly along the outside of thecollar 418. Thismarker 412 assists a user to align the cap 500A with amarker 702 on thesyringe body 302 described below inFIG. 23 . Themarker 412 can alternatively be a recessed groove or surface indicator. A similar marker can be integrated withcap 500. - As depicted, the
collar 418 can have a variable height from the top planar surface to the distal edge. As viewed along the major (X) axis inFIG. 22 , the distal edge can have a pair of opposing convex outward arcs 430. As viewed along the minor (Y) axis inFIG. 21 , the distal edge can have a pair of concaveinward arcs 432. There can be a smooth transition between the convex 430 and concave 432 arcs. Apinch grip 434 having a textured criss-crossed or embossed pattern, or similar surface, is depicted to be present on a side of the cap so as to improve usability. As depicted, thepinch grip 434 can be located on the outer surface along the major (X) axis of the cap. Alternatively, thecollar 418 can have a pair of opposing pinch grips on either end of the major (X) axis. -
FIGS. 23-28 shows anadaptor 704 that can attach to the enteral-only syringe described above. As depicted, theadaptor 704 has abase region 710, amouth region 714 and atransition waist 712 between the base and the mouth. There is anopening 720 through themouth 714 and anopening 730 through thebase 710. As depicted, themouth region 714 andwaist region 712 have a generally circular circumference. Thewaist 712 is depicted to have a smaller diameter than themouth 714. Themouth 714 can include anattachment mechanism 708, for example a threaded outer surface, to attach a standard commercially-available breast pump. - As depicted in
FIGS. 24A and 24B , thebase region 710 can have an elliptical shape similar to thecap collars FIG. 24A shows thebase region 710, as viewed along the minor (Y) axis andFIG. 24B shows the base region as viewed along the major (X) axis. Similarly to thecap collars base region 710 is preferably constructed of resiliently-flexible material, for example plastic. In use, pinching pressure applied simultaneously to the opposing ends of thebase region 710, along the major (X) axis, causes the resiliently-flexible base 710 region to change its shape to shorten the major (X) axis and lengthen the minor (Y) axis. When this simultaneous pressure is released, the resiliently-flexible base region 710 returns to the pre-pressure relaxed state and dimensions. - As depicted, the
base region 710 can include apinch grip 711 on one of the opposing ends of the major (X) axis to improve usability when applying pinch pressure. Alternatively, thebase region 710 can have a pair of opposing pinch grips on either end of the major (X) axis. Thepinch grip 711 can have a criss-crossed, embossed or similar textured appearance. - A
funnel 723 separates, and enables fluid passage between, the interior of themouth region 714 from the interior of thebase region 710. Thefunnel 723 includes a generally-circumferential slide 738 that directs any liquid or material downward towards aport 732. Theport 732 is depicted to be hollow and elongated and has a distal end that extends within thebase region 710 of theadaptor 704. Theslide 738 extends from the inner wall of theadaptor 704 and includes a downwardly-sloped surface. The downwardly-sloped surface extends towards theport 732. Theport 732 is preferably positioned off-center and toward an end of the major (X) axis, preferably near thewaist 712. - A
support 734 extends downwardly away from theslide 738. Thesupport 734 can have a semi-circular wall shape with disconnect similar to thesupports caps support 734 can also be positioned such that theport 732 is situated within the disconnect of the semi-circular wall shape. In use, theport 732 is inserted into the passageway 329 of thechimney 318 in thelid 304. Theport 732 has a narrow diameter preventing the port from creating a, air-tight seal with thechimney insert 318. Theport 732 has a length that allows it to extend through thechannel 377 between theflaps 374 in the seal without forming an air-tight seal. This allows easy introduction of liquid into thesyringe body 302 with simultaneous venting of any trapped air within the syringe body chamber. A distal end of thesupport 734 contacts thelid 304 without applying any pressure to the lid. This alignment of thesupport 734 and thelid 304 assists to prevent theport 732 from inserting an unwanted distance into thechimney 314, as shown inFIG. 26 . The semi-circular shape of thesupport 732 corresponds with the cone shape of thelid 304 to maintain an even distribution of support. - Similarly to the alternative cap 500A described above, the position of the port, funnel and support in the
adaptor 704 can be turned ninety degrees and centered to aligned along the minor (Y) axis. - Similarly to the
caps base region 710. The teeth grips 736 can extend from diametrically opposed locations along the major (X) axis of thebase region 710. Alternatively,additional teeth grips 736 at alternative locations can be effective. The teeth grips 736 are preferably co-molded with theadaptor 704. The shape of the teeth grips 736 is designed to removably insert into thecircumferential groove 312 between thelid 304 and thesyringe body 302. The resilient force of thebase region 710 presses the teeth grips 736 into thecircumferential groove 312 when the base region is in a relaxed state, thus preventing theadaptor 704 from involuntary removal during use. Applying simultaneous inward pinching pressure to opposing ends of the base 710 major (X) axis elongates the minor (Y) axis and removes the teeth grips 736 out of thecircumferential groove 312 so that theadaptor 704 can be removed. Similarly to thecaps ribs 306 in thegroove 312 to prevent theadaptor 704 from rotating within the groove. - The
syringe body 302 can alternatively have amarker 706 that aligns with acorresponding marker 706 on theadaptor 704 when the adaptor is secured to the syringe body. As depicted inFIG. 26 , themarkers syringe body 302 andadaptor 704, however, alternative shapes are considered effective. Themarkers - A commercially-available nipple attachment is shown in
FIGS. 27-29 to secure to thesyringe body 302 through anadaptor 810 described above. Thenipple attachment 800 includes aflexible nipple 802, for example an Abbot®, or Evenflo® brand nipple. Thenipple 802 has acircumferential lip 804 that is secured between a threaded collar/ring 806 and anadaptor 810. When thenipple 802, threaded collar/ring 806 andadaptor 810 are secured to thesyringe body 302, liquid contained within the syringe body can be forced outward through the nipple. - The threaded collar/
ring 806 has a circumferentialtop surface 822 with a central aperture through which thenipple 802 extends upwardly. Thehandle 806 also has acircumferential underhang 824 positioned in a parallel plane beneath thetop surface 822. Agrip surface 820 extends circumferentially perpendicular between thetop surface 822 and theunderhang 824. Afastening mechanism 826, for example a snap-on feature, extends along the inner facing surface of thevertical grip surface 820. The snap-onfeature 826 can secure to a corresponding snap-on on theadaptor 810, as described below. Preferably, the threaded collar/ring 806 is integrally molded as a unitary structure. - The depicted
adaptor 810 includes anouter collar 830 positioned perpendicularly to ashelf 836. Thecollar 830 preferably has an elliptical circumference similar to thecaps shelf 836 can have a generally circular circumference. As depicted, theshelf 836 can have a circumferential wall extending perpendicularly away from the edge of the circular shelf and afastening mechanism 833, for example a snap-on feature, to cooperate with thefastening mechanism 826. Thelip 804 of thenipple 802 is secured between thelid 822 and theshelf 836.Several ribs 838 extend perpendicularly upward from theshelf 836 and align with the interior surface of thenipple 802 to prevent thenipple 802 from collapsing during use. Alternatively, theribs 838 can be a single circumferential structure that lines the entirety of the internal surface of thenipple 802. -
FIG. 29 presents analternative nipple attachment 900 to that shown inFIG. 28 . Theattachment embodiment 900 has a generally-consistent construction, design and function as theattachment 810, but includes an extendedanti-collapse seal 908 instead of theanti-collapse ribs 838. Theanti-collapse seal 908 includes asupport section 904 that conforms to the shape of thenipple 802 and abarrier section 906 that extends from the ends of the support section. Theanti-collapse seal 908 includes a resiliently-sealable aperture 912 near the center of the barrier. Theanti-collapse seal 908 ensures an air-tight seal that allows for use without amovable plunger 808. - Similarly to the
caps adaptor collar 830 is preferably constructed of resiliently-flexible material, for example plastic and has an elliptical shape with a major (X) axis and a minor (Y) axis. In use, pinching pressure applied simultaneously to the opposing ends of the major (X) axis of theadaptor collar 830 causes the resiliently-flexible collar to change its shape to shorten the major (X) axis and lengthen the minor (Y) axis. When this simultaneous pressure is released, the resiliently-flexible collar 830 returns to the pre-pressure relaxed state and dimensions. - A
support 842, similar to thecap 500 described above, extends downardly from theshelf 836. Thesupport 842 can have a semi-circular wall shape with a disconnect and thesupport 842 can be positioned with respect to theshelf 836 such that an enteral-only tip 840 is positioned within the disconnect of the semi-circular wall shape. The enteral-only tip 840 extends from the underside of theshelf 836, as depicted. The enteral-only tip 840 forms an air-tight interference or friction-fit seal with thechimney insert 318, similarly to theplug 516 described above. Acover seal 839 can extend across the opening of the enteral-only tip 840 to prevent entry and exit of ambient air with respect to thesyringe body 302. Thecover seal 839 ensures an air-tight seal that allows for use without amovable plunger 808. In use, when the enteral-only tip 840 is inserted into thechimney insert 318, a distal edge of thesupport 842 contacts thelid 304. This alignment of thesupport 842 and thelid 304 assists to prevent the enteral-only tip 840 from inserting an unwanted distance into thechimney 314. The semi-circular shape of thesupport 842 corresponds with the cone shape of thelid 304 to maintain an even distribution of support. Theport 840 andsupport 842 can be aligned off-center along the major (X) axis within theadaptor collar 830. - A pair of teeth grips 832, similar in design, construction and function to the
teeth collar 830. As depicted, pair ofteeth grips 832 can extend from diametrically opposed locations separated along the minor (Y) axis of thecollar 830. Alternatively, additional pairs of teeth grips at alternative locations can be effective. The teeth grips 832 are preferably co-molded with theadaptor 810. The shape of the teeth grips 832 is designed to removably insert into thecontinuous groove 312 between thelid 304 and thesyringe body 302. The resilient force of thecollar 830 presses the teeth grips 832 into thecontinuous groove 312 when the collar is in a relaxed state, thus preventing theadaptor 810 from involuntary removal during use. Applying simultaneous inward pinching pressure opposing ends of the major (X) axis of thecollar 830 elongates the minor (Y) axis and removes the teeth grips 832 out of thecontinuous groove 312 so that theadaptor 810 can be removed. The teeth grips 832 preferably inserted between the pair ofribs 306 in thecontinuous groove 312 to prevent thecollar 830 from rotating within the groove. - Alternatively, as shown in
FIGS. 30-32 , anipple attachment 962 with a commercially-available nipple 964 secured to a handle can be secured to analternative adaptor 960. Thenipple 964 is secured beneath acircumferential lid 966 with acircumferential handle 968 having an internal threadedsurface 970. Theadaptor 960 has an outer wall with a corresponding circumferential threadedsurface 976 that can secure to the handle threadedsurface 970. Theadaptor 960 includes acollar 972 that is positioned within the circumference of the outer wall circumferential threadedsurface 976. Thecollar 972 has a greater height than the outer wall circumferential threadedsurface 970. Thecollar 972 can have an elliptical circumference with a major (X) axis and a minor (Y) axis. Similarly to the breast-pump adaptor 704 described above, thenipple adaptor 960 has an elongatedport 980 with aproximal opening 989 and adistal opening 991 extending from ashelf 975. Thenipple adaptor 960 also has asupport 978 that is depicted to have a semi-circular wall shape with a disconnect. As depicted, theport 980 is positioned within the disconnect of thesupport 978. Similarly to the alternative cap 500A, theport 980 and thesupport 978 can be centrally-aligned along the minor (Y) axis within thecollar 972. Theadaptor 960 can also include a raised platform or seal 957 secured with respect to the top surface and interfacing with thenipple 964. This raised platform or seal 957 can be a ring-shape constructed of flexible material, for example rubber or silicone. Theseal 957 can have an adjustable dimension, for example diameter, and is preferably ribbed, to allow for venting of trapped air. Thenipple 964 rests with respect to the raised platform or seal 957 so as to allow the venting of air as liquid passes through towards and outward from the nipple. - In use, the
distal opening 991 of theport 980 inserts into thepassageway 320 in the above-describedchimney insert 318 until it forms a friction-fit similar to that with the enteral-only tip 400. The friction fit is air-tight and prevents unwanted material from entering or exiting thesyringe body 302 during use. - The
adaptor collar 972 is preferably constructed of resiliently-flexible material, for example plastic and has an elliptical shape with a major (X) axis and a minor (Y) axis. In use, pressure applied simultaneously to the opposing ends of the major (X) axis of theadaptor collar 972 causes the resiliently-flexible collar to change its shape to shorten the major (X) axis and lengthen the minor (Y) axis. When this simultaneous pressure is released, the resiliently-flexible collar 972 returns to the pre-pressure relaxed state and dimensions. - A pair of
teeth grips 974 similar in design, construction and function to theteeth collar 972. As depicted, the pair ofteeth grips 974 can extend from diametrically opposed locations separated along the minor (Y) axis of thecollar 972. Alternatively, additional pairs of teeth grips at alternative locations can be effective. The teeth grips 974 are preferably co-molded with theadaptor 960. The shape of the teeth grips 974 is designed to removably insert into thecontinuous groove 312 between thelid 304 and thesyringe body 302. The resilient force of thecollar 830 presses the teeth grips 832 into thecontinuous groove 312 when the collar is in a relaxed state, thus preventing theadaptor 810 from involuntary removal during use. Applying simultaneous inward pinching pressure opposing ends of the major (X) axis of thecollar 830 elongates the minor (Y) axis and removes the teeth grips 832 out of thecontinuous groove 312 so that theadaptor 810 can be removed. The teeth grips 832 preferably inserted between the pair ofribs 306 in thecontinuous groove 312 to prevent thecollar 830 from rotating within the groove. - While the invention has been described with reference to preferred and example embodiments, it will be understood by those skilled in the art that a variety of modifications, additions and deletions are within the scope of the invention, as defined by the following claims.
